IMPROVEMENT IN RUBBER DOOR-SPRINGS.

-The Schedule referred to in these Letters Patent and making part of the same.

To all whom Iit may concern:

Be it known that I, JOEL B. HAYDEN, of Schaghtieoke, in the county of Rensselaer and State of New York, have invented a new and useful Improvement in Rubber Springs for Doors and Gates, called Haydcns Rubber Spring, of which the following is a full and exact description, reference being had to the a'ccompanying drawingsformng part ot' these specifications, and in which- Figure 1 shows the position of the rubber spring inside of the door whenthe door' is closed.

Figure 2 shows the action 'of the springr when the door is open, and the tendency of the tension to bring it shut and hold it.

Figure 3 represents the mortise in the back part of the door, for the admission of the spring.

Figure 4 is the rubber spring, with requisite fastenings.

Figure 5 is a anged slide, to fasten the spring to the door-casing.

Figures 6 and 7 represent the requisite fastenings to secure the spring.

Figure S shows the whole complete, and the action of the spring while undergoing tension. A

The invention consists in the combination of a rubber spring with the means, to be hereinafter described, for fastening the same to the door and door-frame.

In order that others skilledin the art to which my invention appertains may be enabled to make and use the same, l will proceed to describe it in detail.

In tbe drawings, tig. 3-

The mortise G is inade in the back part of the door, for the insertion of spring a, fig. 4, which is made of vulcanized rubber, and held toits placein the doorl by.`

passing a screw through the door, and taking the screw-holes in the metal pieces B B', fig. 4, thus fast- -ening it securely in the door'. l

The other end isfastened by means of a piece of metal, with flanged4 sides, G C', ig. 6,ar i d tslot D, 4.

c,The rubber is placed between the flanges G G', and the flat piece E, iig. 7 placed4 on it, so that, when compressed, it sinks between anges C C', and is secured by a screw or rivet passing through piece E and the bottom piece in fig. 6, thus holding it secure.

After the rubber spring is inserted in the door and fastened, as described, the slide F, fig. 5, is put through the slot D, iig. 4, as shown in iig. 8, and fastened to the casing, by screws H and t', as in iig. 8, in the following manner: v

After the ianged' slide F is put through slot D, the door is closed, and the slide F driven into the casing until the tiange comes to its place on the outside of the casing, and is secured by screw H, tig. 8. lben open the door, and insert screw t', iig.u 8l, and-the fastening will be com plete'and strong.

Having thus described my invention,

What I claim as new, and desire to secure by Iletters Patent, is-

In combination with the rubber spring A, the plates B B', for fastening the spring to the door at one end, and the flanged plate G and plate F, for fastening it to the jamh of the door-frame at the other end, substantially a-s described.
